Question 1

How much VRAM does Nous-Hermes-llama-2-7b need?

Accepted Answer

Nous-Hermes-llama-2-7b (6.7B) requires approximately 15.061532592773437 GB of VRAM at full precision (FP16), 7.5 GB at 8-bit quantization (Q8), and 3.8 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run Nous-Hermes-llama-2-7b?

Accepted Answer

We have 10 compatible GPUs indexed for Nous-Hermes-llama-2-7b, including L4, RTX A4000, T4, A40, RTX 3090 and 5 more. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run Nous-Hermes-llama-2-7b?

Accepted Answer

The cheapest GPU to run Nous-Hermes-llama-2-7b in the cloud is the L4 at $0.20/hr. Other affordable options include RTX A4000 ($0.25/hr) and T4 ($0.35/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Nous-Hermes-llama-2-7b run on consumer hardware?

Accepted Answer

Yes, Nous-Hermes-llama-2-7b can run on consumer GPUs like the RTX A4000 (16 GB VRAM) at full precision (FP16). Other compatible consumer GPUs include RTX 3090 and RTX A4500.

Question 5

What quantization options are available for Nous-Hermes-llama-2-7b?

Accepted Answer

Nous-Hermes-llama-2-7b supports the following quantization levels: FP16 (full precision): ~15.061532592773437 GB, Q8 (8-bit): ~7.5 GB, Q6 (6-bit): ~5.6 GB, Q4 (4-bit): ~3.8 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression.
